Dr D is texting a "girl" on his phone, smiling his little "ooh baby" smile, and looking quite smug.
Me: "Oh look at you, with the big grin, trying to look all intelligent now"
Dr D: "I don't have to try to look intelligent, it's a given. So there lower IQ girl, since mine is higher than yours"
Me: "Only by 1 point you know"
Dr D: "Yeah but a point's a point, and I'm smarter so nyer".
